Attessa Priming Time

[djrobertshaw]

Hi,

I know there has been alot of topics about bleeding the attessa system and various errors but I cant seem to find the answer I am after.

I have recently had the CV boots changes and a PFC installed (shouldnt be relevant) on my r33 GTR, since then I have noticed the priming time first thing in the morning has increased. It can take 15seconds to shut off.

Not 4wd lights and no issues but just concerned it may need bleeding.

I have checked and topped up the reservoir.

Really just need to know if changing CV can leak fluid and require attessa system to be bled (I am clearly no mechanic)? and what the normal prime time is?

Thanks,

Dean

CVs are at some distance from the transfer case and so there should be no possible way for changing just the CVs to cause the ATTESSA change you've seen.

Far more likely is that the PFC is not communicating with the ATTESSA CU like the factory ECU does and the ATTESSA CU has fallen back on some default or other. Put the factory ECU back in, turn the ignition on, and report back.

Re aftermarket ecus in general I just know that the guy who installed my Link said he had to run a wire from the TPS for the Attessa but sorry can't tell you more!
